Overview
"I Love Lisa" is the fifteenth episode of the fourth season of the American animated television series The Simpsons. It originally aired on the Fox network in the United States on February 11, 1993. In the episode, Lisa gives Ralph Wiggum a Valentine's Day card when she sees that he has not received any. Ralph misinterprets Lisa's gesture and, much to Lisa's dismay, relentlessly pursues her with affection. Lisa snaps at Ralph and angrily tells him they are not together and that she never liked him. Heartbroken, Ralph channels his feelings into his performance as George Washington in the school's President's Day pageant. After a thunderous applause from the audience, he is able to accept Lisa as just a friend.
The episode was written by Frank Mula and directed by Wes Archer. Michael Carrington guest-starred as Sideshow Raheem. Al Jean, show runner of the episode, came up with the idea for the story when he remembered that he had received a valentine from a girl in third grade that read "I Choo-Choo-Choose You". The episode features cultural references to songs such as "Monster Mash" and "Break on Through", as well as a reference to the fictional character Droopy.
Since airing, "I Love Lisa" has received mostly positive reviews from television critics; Entertainment Weekly placed the episode twelfth on their top 25 The Simpsons episodes list. It acquired a Nielsen rating of 14.9 and was the highest rated show on the Fox network the week it aired.

On Valentine's Day, Lisa's class at the Springfield Elementary School constructs paper mailboxes for the Valentine cards they are about to receive from each other. When Ralph cries after getting no cards, Lisa gives him one out of sympathy. Ralph cheers up, develops a romantic interest in Lisa, and walks her home from school. This leaves her feeling nervous around him, not knowing how to tell him she is not interested.
